"In the beginning it was dead. “Depleted, polluted, dysfunctional” is how
Isabella Tree describes the farm that she and her husband helped nature to
recolonise.

Recolonise it has. According to a two-decade ecological review of the Knepp
rewilding estate in Sussex, England – published this week – the 3,500-acre site
has recorded a 900% increase in breeding birds.

Among them imperilled species such as the turtle dove (main picture) and
nightingale, which have experienced shocking declines across much of the UK,
but saw their numbers increase by 600% and 511% respectively at Knepp.

“The trend is strongly positive and still increasing year on year,” said Fleur
Dobner, a Knepp ecologist.

The review points to “a dramatic recovery in wildlife”, revealing how butterfly
numbers have doubled in some areas, while dragonflies and damselflies have
increased by nearly 900%."
